Abstract:

The Tuberculosis in Animals Subsection of the International Union Against Tuberculosis and Lung Disease (IUATLD) recently identified a need to standardize the deoxyribonucleic acid (DNA) strain typing of Mycobacterium bovis. The standard method for strain typing of M. tuberculosis isolates cannot be directly extrapolated to M. bovis due to the low copy number of IS6110 identified in the majority of M. bovis strains, particularly from cattle. To improve the resolution of M. bovis strains, alternative methods and additional DNA probes have been investigated. In combination with studies of published literature, laboratories performing M. bovis DNA fingerprinting were surveyed. Results of these surveys allowed us to reach consensus and to make recommendations for DNA typing of M. bovis isolates, which hopefully will lead towards a standardized approach to the DNA fingerprinting of this organism. This approach, in conjunction with conventional epidemiological traceback approaches, should facilitate more accurate and effective investigations into the epidemiology, maintenance and transmission of M. bovis within and between man and domesticated, feral and wild animals, both at a local and a global level.
